We note that, if contradictory information are available, we always choose to apply the [1]} criteria in the most severe way. For example, in [2]} the sample of [3]} was studied in more details, computing \(r_{200}\)  in two different ways: one obtained from weak lensing analysis and the other from X-ray data. The latter is found to be \(\sim 50\%\)  larger than the former. As a consequence, the number of FGs found using the smallest radius is 10, a number that reduces to 3 if the largest radius is used. In order to provide the cleanest sample of genuine FGs, we include in Table REF  only the 3 obtained with the largest \(r_{200}\) , citing only [2]}, even if most of the candidates were also present in [3]}. This choice is done in order to direct the reader to the most up-to-date and/or relevant information.
